Let's divide 256831 by 17
We're looking to find how many times 17 goes into 256831.

Moving on to step 1:
The number 17 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 17

Moving on to step 2:
The number 17 fits into 25 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 17 from 25 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 17

Moving on to step 3:
17 goes into 86 5 times with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 1 after subtracting 85 from 86.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 17

On to step 4:
17 goes into 18 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 151.0
Deduct 17 from 18 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 17

Let's proceed to step 5:
13 divided by 17 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 1510.0
If we take 0 away from 13, we end up with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 17

Let's proceed to step 6:
131 divided by 17 is 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 15107.0
If we take 119 away from 131, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 17, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 15107.7
Subtracting 119 from 120 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
17 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15107.7
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
17 can be fit into 100 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15107.705
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 15107.7058
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
140 divided by 17 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 15107.70588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 15107.70588 with a remaining 4e-06.
